Ellipse perimeter

Perimeter is the distance around a two-dimensional shape.

Ellipse — is a closed curve on a plane that can be obtained as the intersection of a plane and a circular cylinder or as an orthogonal projection of a circle onto a plane.

To find the perimeter of an ellipse, we need to find the length of two semi-axes or the length of two axes of an ellipse (maximum and minimum length of an ellipse). After we know the indicated values, we can apply the above formula for calculating the perimeter of an ellipse.
